Specification of Letters Patent.

Application filed May 9, 1918. Serial No. 766,615.

To all whom it may concern Be it known that I, CHARLES Win/[Briancitizen of the United States, residing at Concord, in the ,county ofContra Costa and State of California, have invented new and usefulImprovements in Portable Knockdown Stoves, of which the following is aspecification. This invention relates to portable, knock-- down orcollapsible stoves, the stove being especially designed with referenceto the needs of campers, prospectors, outing and automobile parties andthe like, the objectin view being to produce a stove of the knock-downvariety which will embody practical utility, lightness and durabilityand be capable of production at a reasonable cost.

A further object of the invention is to provide a stove of theknock-down variety which, when all the parts thereof are assembled inproper relation to each other will be effectively braced, the said stoveembodying means providing for an adjustment of the draft whereby thefire may be accurately regulated and taken care of.

The stove as a vwhole will be found especially valuable in preventingforest fires, there being no escape for the burning embers. J

With the above and other objects in view the invention consists in thenovel construction, combination and arrangement of parts herein fullydescribed, illustrated and claimed.

In the accompanying drawings :Figure 1 is a perspective view of thestove of this invention set up in readiness for use. Fig. 2 is avertical longitudinal section through the same. Fig. 3 is a verticalcross section thereof showing the spreader rod in its relation to theother parts of the stove. Fig. 4 is an end elevation of the stoveshowing the door, the draft opening, and the closure for said opening.Fig. 5 is a detail view of the main section folded. Fig. 6 is a similarview of the door section folded. Fig. 7 is a detail view of the fluewall section folded.

The stove contemplated in this invention is composed in the main ofsheet metal as 1 designates the top of the stove which is provided withany suitable number of stove holes 2 according to the size of the stoveit being understood that the stove as a whole may be made in varioussizes to suit the manufacturer.

The sides 3' which, like the top 1 are 'of sheet metal, are'connected attheir top edges by knuckle joints 4 to the opposite longitudlnal edgesof the top 1, whereby the sides are adapted to be setat right angles tothe the reduced and shouldered ends of a .ties of the rod bearingagainst the inner surfaces of the sides so as to hold the same spreadapart as shown in Fig. 3. The extremities of the rod project outside ofand beyond the sides 3 for a purpose which will hereinafter appear.

The stove also embodies the front end wall 10 and the rear end or theflue wall 11. The front wall 10 is provided at its opposite edges withside flaps 12 which are hinged to the front wall at 13, adapting thesaid flaps to be folded flat-wise against the front Wall or swungoutwardly to a position at right angles to the front wall so as toembrace the sides 3 of the main section of the stove. The flaps 12 areprovided in their bottom edges adjacent to the hinges 13 with notches 14which provide shoulders 15. The notches 14 enable the flaps 12 to setover the projecting extremities of the spreader rod 7 while theshoulders 15 engage said extremities of the rod and serve to lock theflaps and thereby the front wall 10 to the main section of the stove.The front wall 10 is provided with a door opening 16 and a hinged door17, and the latter is provided with a draft I opening 18 and a closure18' therefor to pro vide for regulating draft through the body of thestove. The other end wall 11 is correspondingly provided with side flaps19 adapted 'to embrace the sides 3 of the stove at that end, said flapsbeing hinged to the wall 11 as shown at 20 to adapt them to be foldedflat-wise against the wall 11. The end wall 11 is extended to anydesired Patented Jan. 13, 1914.

. through the holes 6. The flaps 12 and 19 of the end walls are thenfolded outwardly at right angles to said sides and are slid over thesides 3 of the main section of the,

stove as shown in Fig. 1. The wall 11 is set at a suitable distance fromthe corresponding end of the top 1 and sides 3 to leave a draft openingas shown in Fig. 1 which draft opening. is protected by the combinedflue wall and fender or wind shield 21. The closure 18 is then opened tothe desired extent to provide the necessary draft through the stove fromend to en When the stove is not in use, the several parts thereofreferred to are disconnected and the hinged sides and flaps referred toare folded flat-wise against their respective members and the sectionsof the stove are piled one upon another, forming a compact bundle whichmay be easily and conveniently stored and transported until required forfurther use.

If desired the front wall 10 may be provided along its top edge withaninwardly extending flange 22 adapted to rest on the top- 1 of thestove. Furthermore the top 1 and sides 3 may be reinforced by means ofbraces -23 preferably riveted or otherwise fixedly secured to the innersurfaces of the said parts.

What is claimed is:-

1. A portable sheet metal knock-down stove comprising a top, two sideshaving a knuckle jointed connection therewith adapting the sides to befolded flat-wise against the top, a spreader rod extending transverselyand horizontally across the stove and having its ends reduced andshouldered to pass through holes near the bottom edges of the sides andproject outside of the same, and separable end walls each provided withside flaps hinged thereto and adapted to embrace the sides of the stove,the flaps of one end wall being formed with shoulders which interlockwith the projecting extremities of the spreader. rod.

2. A portable sheet metal knock-down stove comprising a top, two sideshaving a knuckle jointed connection therewith adapting the sides to befolded flat-wise against the top, the top bein provided with stopshoulders to limit t e outward opening movement of the sides, a spreaderrod extending transversely and horizontally across the stove and havingits ends reduced and shouldered to pass through holes near the bottomedges of the sides and project outside of the same, and separable endwalls each provided with side flaps hinged thereto and adapted toembrace the sides of the stove, the flaps of one end wall being formedwith shoulders which interlockwith the projecting extremities of thespreader rod.

3. A portable sheet metal knock-down stove comprising a top, two sideshaving a knuckle jointed connection therewith adapting the sides to befolded flat-wise against the top, a spreader rod extending transverselyand horizontally across the stove and having its ends reduced andshouldered to pass through holes near the bottom edges of the sides andproject outside of the same, and separable end walls each provided withside flaps hinged thereto and adapted to embrace the sides'of the stove,one end wall being slidablerelatively to the remainder of the stove andbeing extended above the top of the stove to form a combined draft fluewall and fender.

4. A portable sheet metal knock-down stove comprising a top, two sideshaving a knuckle jointed connection therewith adapting the sides to befolded flat-wise against the top, a spreadcd' rod extending transverselyand horizontally across the stove and having its ends reduced andshouldered to pass through holes near the bottom edges of the sides andproject outside of the same, separable end Walls each provided with sideflaps hinged thereto and adapted to embrace the sides of the stove, theflaps of one end wall being formed with shoulders which interlock withthe projecting extremities of the spreader rod, the other end wall beingprovided with a draft inlet opening, and a damper for closing saidopening.

In testimony whereof I aflix my signature in presence of two witnesses.
